Answer:
36.5
Option A is the correct option
Step-by-step explanation:
In ∆ABC , <A = 51°
For <A = AC = adjacent = X
AB = hypotenuse = 58
Now,
[tex]cos \: theta \: = \frac{adjacent}{hypotenuse} [/tex]
[tex]cos \:a \: = \: \frac{x}{58} [/tex]
[tex]cos \: 51 = \frac{x}{58} [/tex]
[tex]x = 58 \: cos \: (51)[/tex]
[tex]x = 36.5 \: (to \: the \: nearest \: tenth)[/tex]
Hope this helps...
Good luck on your assignment...
